CEA Updates Characteristics for Ultra High-Definition Displays
NEW YORK --(Business Wire)--
The Consumer Electronics Association (News - Alert) (CEA)® today announced
updated core characteristics for Ultra High-Definition (UHD) TVs,
monitors and projectors for the home. As devised and approved by CEA's
Video Division Board, these characteristics build on the
first-generation UHD characteristics released by CEA in October 2012.
These expanded display characteristics (CEA's Ultra High-Definition
Display Characteristics V2) - voluntary guidelines that take effect
in September 2014 - are designed to address various attributes of
picture quality and help move toward interoperability, while providing
clarity for consumers and retailers alike.
"Ultra High-Definition TV is the next revolution in home display
technology, offering consumers an incredibly immersive viewing
experience with outstanding new levels of picture quality," said Gary
Shapiro, president and CEO, CEA. "These updated attributes will help
ensure consumers get the most out of this exciting new technology and
will provide additional certainty in the marketplace."
Under CEA's expanded characteristics, a TV, monitor or projector may be
referred to as Ultra High-Definition if it meets the following minimum
Display Resolution - Has at least eight million active pixels,
with at least 3840 horizontally and at least 2160 vertically.
Aspect (News - Alert) Ratio - Has a width to height ratio of the display's
native resolution of 16:9 or wider.
Upconversion - Is capable of upscaling HD video and displaying
it at Ultra High-Definition resolution.
Digital Input - Has one or more HDMI inputs supporting at least
3840x2160 native content resolution at 24p, 30p and 60p frames per
second. At least one of the 3840x2160 HDMI inputs shall support HDCP
revision 2.2 or equivalent content protection.
Colorimetry - Processes 2160p video inputs encoded according to
ITU-R BT (News - Alert).709 color space and may support wider colorimetry standards.
Bit Depth - Has a minimum color bit depth of eight bits.
Because one of the first ways consumers will have access to native 4K
content is via Internet streaming on "connected" Ultra HDTVs, CEA has
defined new characteristics for Connected Ultra High-Definition
displays. Under these new chracteristics, which complement the updated
core UHD attributes, a display system may be referred to as a Connected
Ultra HD device if it meets the following minimum performance attributes:
Ultra High-Definition Capability - Meets all of the
requirements of the CEA Ultra High-Definition Display
Characteristics V2 (listed above).
Video Codec - Decodes IP-delivered video of 3840x2160
resolution that has been compressed using HEVC* and may decode video
from other standard encoders.
Audio Codec - Receives and reproduces, and/or outputs
IP and Networking - Receives IP-delivered Ultra HD video
through a Wi-Fi, Ethernet or other appropriate connection.
Application Services - Supports IP-delivered Ultra HD video
through services or applications on the platform of the manufacturer's
Ultra High-Definition TV is the closest thing to bringing the 4K Digital
Cinema experience from movie theaters to the home, offering consumers an
incredibly immersive viewing experience with superior picture quality
compared to current HD displays. UHD TVs, projectors and monitors
provide the ultimate viewing experience with more than eight million
pixels of resolution, four times the resolution of today's
high-definition televisions, as well as other technical improvements
designed to result in an unparalleled home entertainment experience for
CEA's expanded display characteristics also include guidance on
nomenclature designed to help provide manufacturers with marketing
flexibility while still providing clarity for consumers. Specifically,
the guidance states, "The terms Ultra High-Definition, Ultra HD or UHD
may be used in conjunction with other modifiers," for example 'Ultra
High-Definition TV 4K'.
In addition, CEA is working with its member companies to develop a UHD
logo to assist consumers in identifying UHD products in the marketplace
that meet CEA's guidelines. The logo will be made available for
voluntary use by manufacturers for product packaging, marketing
materials and promotional activities. The companion voluntary logo
program is expected to be launched later this year.
*High Efficiency Video Compression Main Profile, Level 5, Main tier, as
defined in ISO/IEC (News - Alert) 23008-2 MPEG-H Part 2 or ITU-T H.265, and may support
higher profiles, levels or tiers.
